I was recording an intro video about myself to send to people, typing up a document while screen recording, and I typed "faliure" instead of "failure". Couldn't get it right. I just sat there staring at it. That's when I thought, what if the font just fixed it for me?
So I made Autocorrect. It's a font that corrects common misspellings. You type the wrong thing, the font shows the right thing. No spellcheck needed. Works in most apps. Based on Instrument Sans by Rodrigo Fuenzalida. Free under the SIL Open Font License.
